OpenSource IPTV MPEG2-TS analyzer. This presentation was given at OpenSourceDays 2010 (and in earlier stages of the project at Bifrost Workshop 2009 and 2010)

1. Open Source Days 2010 d.6/3-2010 ComX Networks A/S by Jesper Dangaard Brouer <jdb@comx.dk> Master of Computer Science ComX Networks A/S

5. Part1: about trouble shooting IPTV network problems

6. Part 2: about developing our own IPTV monitor probe

7. Future plans for an IPTV shaper

14. CPE equipment needs IGMP snooping, more Settop boxes

16. More than 120 IPTV channels

24. Desperate clear PIM cache drills

27. Slow and expensive support

28. Kickoff IPTV probe/shaper project based on Linux

33. Wireshark IO-graph with resolution < 1 ms

34. Implemented drop detect our selves in Wireshark

35. (the power of open source)

39. Function: “ t packet_rcv” (See /proc/net/ptype)

41. Non-bursty streams are affected by bursty-streams

42. On Linux: Use Highres timers and no tick

45. Bursts can cause drops, on all channels

50. Collector daemon (Perl)

51. Database design, storing events (MySQL)

52. Web based frontend (PHP)

53. Trick: use settop boxes as probes (bash)

54. IPTV Probe architecture

56. Only uses 2% CPU with 600Mbit/s traffic

57. on a low power ATOM 330 CPU (1.6Ghz)

62. PHP developers needed on the project!

63. Web-frontend: Probe overview

64. Web-frontend: Channel view

68. Settox boxes as probes

76. Fixed size packets of 1358 bytes on wire

77. Know you switch buffer sizes

78. don't place small-buffer switches in backbone
